IMPROVEMENT IN DOOR- REGISTERS.

Specification forming part of Letters Patent No. 172,762, dated January25, 1876; application filed December 23, 1875.

To all whom it may concern Be it known that I, FELIX MYERS, ofPhiladelphia, Pennsylvania, have invented an Improved Registering-Door,of which the following is a specification:

The object of my invention is to construct for public buildings, cars,&c., a'simple and effective registering-door, which will afl'ord thesame facilities for ingress and egress as an ordinary door; and thisobject I attain in the manner which I will now proceed to describe,reference being had to the accompanying drawing, in which Figure 1 is aperspective view of my improved door; and Figs. 2, 3, 4, and 5,sectional plan views with the parts indifferent positions.

A is a hinged door, and B a circular cage or box, carried by and formingpart of this door, and projecting partly on the outside and partly onthe inside of the same.

The cage B is composed of a series of segmental sliding doors, D, E, F,and G, which are acted upon by suitable springs d, e, f, and g, thetendencies of the latter being to maintain the doors in the positionsshown in Fig. 2, so as to partly inclose the outer portion of the cageand entirely inclose the inner portion.

The doors D and E are guided at the lower edges by grooves in thecircular base-plate a of the door, and at the top by similar grooves ina semicircular bar, I). The door F is guided by a groove in the plate a,and in the semicircular plate c, which forms the top of the inner halfof the cage, while the door G is guided by a groove at the bottom, butis attached at the top to the said plate 0, and partially turns the samewhen it is moved.

The spring g, which is used to insure the return of the door G to itsnormal position, Fig. 2, consists of a strip of rubber or other elasticmaterial, and acts upon the door through the medium of a pulley, h,attached to the plate 0, and connected, also, to the rod 1', by whichthetop of the cage is pivoted, so that any movement of the door G'isnecessarily transferred to this rod i.

The movement of the rod 2' in the direction of the arrow, Fig. 1, causesthe operation of a suitable registering device, I, attached to the doorA; but the movement of the rod in the opposite direction does not affectthe register.

The door F is provided with a spring-catch, k, or other suitable locking deyice, which can be opened only from the inside of the cage; and thedoor G has a similar locking. device, m, which can be opened only fromthe inside of-the apartment to the door of which the device is applied,or 'from the 7 interior of the cage, by means of a suitable key.

The catch 70, when closed, prevents the movement of the door F- in thedirection of the arrow, Fig. 4, and the catch m prevents the movement ofthe door G in the direction of the arrow, Fig. 5, but these catches areso arranged that they will not interfere with the movement of the doorsin the opposite direc tions.

The door A has a suitable look, so that anthorized persons may enter theapartment through this door without operating the registering apparatus.

The operation of the above-described device is as follows: A personwishing to enter the apartment moves back the doors D and E, as shown inFig. 3, and enters the interior of the cage, the doors closing behind,owing to the action of their springs. The lock it is then opened and thedoor F moved around in the direction of the arrow, Fig. 4, and, when thespring f has been compressed, this motion is communicated to the door G,which also slides until it reaches the position shown in Fig. 4,causing, meanwhile, through the medium'of the plate 0 and pulley b, amovement of the rod '5 in the direction of the arrow, Fig. 1, and aconsequent operation of the registering device I. As the person entersthe apartment the doors F and G, owing to the action of the springs fand g, return to the position shown in Fig. 3, ready to register theentrance of another person.

. Any one desiring to leave the apartment first opens the lock m fromthe interior, and then moves the door G in the direction of the arrow,Fig. 5, this motion being also communicated to the door F, untilthey-both reach the position shown. in Fig. 5, when a space is presentedlarge enough to permit the entrance of the person, behind whom the doorsclose.

. The doors 1) and E are now moved back by the person Within the cageuntil they reach the position shown in Fig. 3, and do not interfere witha free exit.

The conductor of a car or any other authorized party can enter withoutregistering by simply unlocking the door A and opening the same, or byfirst entering the cage, and then opening the lock m by means of asuitable key, so as to permit the opening of the door G.

The spaces for entrance to and exit from the cage B are such that, whilethey readily allow the passage of one person, they will not permit theentrance of more than one at a time; and, on reference to the drawing,it will be seen that the doors D E and F G are so arranged that, whenopen, they abut against each other, thereby preventing both the entranceand exit openings of the cage from being open at the same time.

An important feature of my invention consists in combining theregistering-cage B with an ordinary door, A, as this allows the rapidexit of the occupants of the apartment when they desire to leave in abody.

' Insome cases, Where the cage B is of large size, the doors F and G maybe made inde- 2. The cage B, projecting on both sides of a door orpartition, A, and provided on the outside with spring-doors D E, and onthe inside with spring-doors F G, the latter being connected to theregistering apparatus.

3. The combination ofthe cage B with the doors F and G, the former beingprovided with a lock which can only beopened from the inside of thecage, and the latter with a lock which can only be opened from theinside of the apartment to which the door is applied, all as and for thepurpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FELIX MYERS.
